Hello All,
Could someone advise if these SMA terminators are good ?
I've done a resistance check at DC using multimeter and it's shown 68 Ohms (too high by me, should be lower).
Secondly, I've attached to VNA (properly calibrated with other known good 50 Ohm SMA) and the result is:
1. At frequencies lower than 100Mhz SWR is 1.3.
2. In 1Ghz range has significant capacitance impedance.
The item is rated DC-18Ghz TRM-2444-M0-SMA-02 (specs https: www.mouser.co.uk/datasheet/2/643/pi-CCS-MW-TRM-2444-M0-SMA-02-1312942.pdf)
Am I doing something wrong or terminators are defective ?
Pictures attached.
Regards,
Constantin
